As the first American case of Ebola was confirmed in Dallas yesterday, some laid blame on the Obama administration’s lax immigration policies for the ease at which the illness penetrated the nation’s borders.

During the past year, the federal government has struggled to deal with an influx of immigrants, 75 percent of which have arrived from countries other than Mexico.

The scale of diseases entering the US became apparent earlier this year when several Border Patrol agents working in crowded detention facilities began contracting illnesses, such as H1N1 swine flu, scabies and chicken pox, stemming from contact with diseased illegals.

Indeed, as more cases of tuberculosis and other contagious illnesses surfaced, experts began predicting that, given the lack of border security enforcement and health screenings, viral outbreaks occurring in parts of the world such as West Africa had a higher chance of reaching the U.S.

“Why are more doctors in the southern border states not already on alert to handle sudden increase in TB, adult chicken pox, measles, H1N1 influenza, dengue, Ebola, plus other unknown but lethal diseases?” asked practicing medical doctor Elizabeth Lee Vliet back in June.

Dr. Vliet and a host of politicians and medical professionals, including radio host and epidemiologist Michael Savage, were long ago warning of the dire threats posed to public health by the Obama administration’s de facto open border policies, which allowed illegals into the U.S. absent proper health screenings.

“These diseases are highly contagious,” wrote Vliet, “especially in crowded and poor sanitary conditions in the detention and processing centers where thousands of illegals are housed until sent to other areas of America, without full screening for such diseases.”

Others, such as Texas Rep. Phil Gingrey, expressed concerns that “the border poses many risks, including grave public health threats.”

“Reports of illegal migrants carrying deadly diseases such as swine flu, dengue fever, Ebola virus and tuberculosis are particularly concerning,” Gingrey wrote in a letter to the CDC back in July.

While the CDC claims the Ebola patient did not cross through the southern border, last month, Dr. Vliet cast a prediction that the “global array of viral illnesses,” in addition to the nation’s porous borders, were a recipe for disaster.

“Ebola is one of the most lethal diseases we face, with a death rate from 60-90 percent of infected patients. It is a horrible death as the virus attacks the blood vessels leading to hemorrhaging internally and externally. There are no good treatments or vaccines,” she wrote.

Additionally, the doctor highlighted, the CDC unbeknownst to the public has already established emergency health facilities across the country to deal specifically with an Ebola outbreak.

“If risk is so low for the U.S., why is the CDC quietly setting up Ebola Quarantine Centers in 20 cities across the U.S.? Why did the Congressional Record report that Ebola bio kits have been deployed to National Guard units in all 50 states?” Dr. Vliet questioned last month.
